Another thing I noticed with the post editor is the remove formatting button doesn't always show the effect of the size tags being removed. I switch over to editor mode and it shows the size code tags are gone, and eventually when I preview the post the text shows up as intended. Just confusing because it gives the appearance the size tags weren't removed.

Whenever you get back from killing jedis, sith, bounty hunters, and mandalorians, I guess you're going to take your millions earned from the Amazon ad to buy and install vbulletin 3.8.6 that was specifically updated to fix this size code tag problem.
